ANET A8 BELT TENSIONER and BRACE Y-Axis
We added this one so people in the community could provide feedback. When we finalize the model we will publish the final version.
The nut traps are very tight. Position the nuts in front of the traps and then use the 12mm screws to draw them in.
When the belt is taught – thread lock can be added to the nut/bolt to secure it in place.

Carbon Fiber Y-Axis tray Chain Anchor & Lock 3D Print Model
Summary
This is a cable chain anchor and mount for a cable chain that fits the Carbon Fiber Y-Axis tray. (https://www.amazon.com/gp/product/B071LTS8W8/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B071LTS8W8&linkCode=as2&tag=communityhost-20&linkId=bed5896d95b8d2ced89cca68414f32f9)
The CF tray zip tie slot is about 3mm further in than the stock aluminum tray zip-tie slot, so all of the cable chain anchors out there won’t work. Additionally, if you’ve installed the removable build plate by billyd (https://www.thingiverse.com/thing:1021403) and used the aluminum carriage upgrade (https://www.amazon.com/gp/product/B0192K4N6K/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B0192K4N6K&linkCode=as2&tag=communityhost-20&linkId=1e61bce087154c48393fc54d8e997803), the aluminum carriage is too close to the CF tray to allow a standard mount in there anyway.
So this mount is inverted (screws on the bottom, instead of the top), and thinned enough to allow clearance for bed-leveling of the tray.
It’s pretty straightforward on install, just upside down from a normal anchor for a cable chain.

Anet A8 adjustment for Y-axis and printer leveling 3D Print Model
Summary
I’ve had the problem the floor on which the table for the printer stood wasn’t leveled. Which led to corners at the z-axis which haven’t had 90°. The same happened at the y-axis, because the threaded bars are bent.
If you just have a problem with a bend y-axis:Parts List:
Wooden board
10x screws for wood 3×12
1x M3x30
2x washer for M3
1x nut for M3
Angle profile length ~240mm
First cut the angle profile in two parts of ~62mm length and two parts of ~50mm length.
Drill in every part two holes and screw the ~62mm parts at the front of the housings and the ~50mm parts at the sides.
Print the STL, put the M3 screw with the washers and the nut in the small hole and screw it onto the wooden board near the side of the frontplate of the y-axis. Use the M3 screw to adjust the y-axis.
If you also have problems that your printer isn’t levelled perfect horizontally:
Parts List:
4x screwable case legs
Drill 4 holes in the corners of the wooden board by following the manual of the case legs. Use a water bubble to level the board.

TronXY P802E Y-Axis Cable Chain Remix 3D Print Model
Summary
I saw a number of chains for various frames for the TronXYs but none that fit for the P802E specifically. After printing a couple that didn’t quite fit properly, i ended up remixing the designs of two other chains. This fits properly and doesn’t fray your bed cable.
